How to Make Vegetable Soup
Follow these simple steps for perfect results every time. Remember to taste and adjust seasonings before serving.
Step 1: Sauté Aromatics
Heat oil in a large soup pot over medium heat. Add diced onions and cook for 1-2 minutes until translucent. Stir in minced garlic and cook 30 seconds until fragrant but not browned.
Step 2: Build the Broth
Pour vegetable broth into the pot with potatoes, diced tomatoes, tomato sauce, parsley, oregano, thyme, salt, and pepper. Bring to a vigorous boil over medium-high heat.
Step 3: Simmer Vegetables
Reduce heat to medium-low. Add frozen mixed vegetables directly to the pot without thawing. Simmer uncovered for 20-25 minutes until potatoes pierce easily with a fork. Serve immediately.
Pro Tips for Success
Apply these professional kitchen tricks to elevate your vegetable soup game:
- Cut potatoes into uniform ½-inch cubes so they cook evenly
- Layer salt little by little – broths vary in sodium content
- Add a parmesan rind while simmering for umami depth (optional)

- Finish with fresh herbs like basil or parsley for brightness

FAQs About Vegetable Soup
Can I use fresh vegetables instead of frozen?
Absolutely! Use 3 cups fresh vegetables. Add sturdy veggies like carrots with the potatoes, and delicate ones like zucchini during the last 5 minutes.
How can I make this soup creamier?

Yes! Sauté onions and garlic first, then add all ingredients except frozen veggies to slow cooker. Cook on low 6 hours or high 3 hours. Add frozen vegetables last 30 minutes.
